JOI-lhT O. KELLOGG, OF LEXINGTON, KENTUCKY, ASSIGNOR OF ONE-HALF TOALFRED L. l-IARTING, OF SAME PLACE.

TROLLEY FOR ELECTRIC CARS.

SPECIFICATION forming part of Letters Patent No. 585,579, dated June 29,1897'.

Application led September 25, 1896. Serial No. 606,931. (No model.)

To all whom t may concern/.-

Beit known that I, JOHN C. KELLOGG, a citizen of the Unit-ed States, anda resident of Lexington, in the county of Fayette and State of Kentucky,have invented certain new and useful Improvements in Trolleys forElectric Cars; and I do hereby declare that the folv lowing is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification. g

My invention relates to improvements in trolleys for electric cars; andits object is to provide an improved construction of the same wherebythe conducting-wire is guided to the trolley-wheel, so as to insure itsquick engagement therewith, and in case the wheel should jump the wireit is easily caught and in catching the wire it cannot become entangledwith the wire.

The invention consists, essentially, in a flaring fork having twoparallel arms which are journaled to the axle of the trolley-wheel andextending down below the same and provided with a yoke or bail withwhich the rope by which the trolley is depressed and elevated issecured, the construction being such that when said rope is pulled downthe forks will be thrown up, so as to guide the wire to the wheel, andwhen the 4rope is released the forks will be thrown back, so that thewheel will contact and engage with the wire.

It also consists in providing said forks with two downwardly-extendingspring-arms located between the harp and wheel, which by theirfrictional contact with the inner sides of the wheel hold the fork inplace when thrown back, all as hereinafter fully described and claimed.

In the accompanying drawings, Figure l is a perspective view of the harpand trolley* wheel of an electric trolley-car, showing my improvementsapplied thereto. Fig. 2 is a central cross-sectional view of the same.Fig. 3 is a side elevation.

In the said drawings the reference-numeral l designates a rod whichengages with the upper end of a trolley-pole, (not shown,) which ispivotally connected with the top of a car, as usual. The numeral 2designates the harp secured thereto, provided at the upper end with atransverse shaft 3, upon which is j ourualed the trolleynwheel 4. Theseparts may beof any ordinary or suitable construction and form no part ofthe present invention. Journaled on said shaft at each side of the harpis an arm 5,which extends above and below the shaft. `At the upper endsthese arms are securely connected with a fork G, consisting of a fiatmetal bar bent over at the center, forming two outwardly-extending oriiaring arms at an acute angle to each other. A space of about eightinches, more or less, is thus formed between the ends of said arms. Alsosecured to said fork are two spring arms 7, having apertures throughwhich the shaft 3 passes. The tendency of these arms is tospringinwardly and clasp the wheel, so that when the wheel rolls back itwill throw the forks back and hold them down by the friction on thesides of the wheel. l

Formed near the lower ends of the arms 5 and a little tov one side of aline drawn vertically through the center of the fork is a'hole 8, withwhich is pivotally connected a bail or yoke 9, to which the rope 10,bywhich the trolley-wheel is raised and lowered,is secured.

Thel operation is as follows: W'hen the trolley pole and wheel arepulled down and away from the conductor or wire, the rope, drawing uponthe lower ends of the arms 5, will turn the same on the axle to whichthey are journaled, throwing the fork up, as seen in Fig. l. The rope isheld tight until one or both of the Haring arms catch the wire andconduct it to the wheel. Then let go the rope and the wire forces theforks back, and the springs hold it back by the friction of the wheel.In other words, it is a shield when catching the wire, so that the harpand wheel cannot get fast, as they often do.

The spring-arms will hold the fork in place and prevent it fromjumpingup and engaging with the wire. They will also hold the fork in position,when the rope is released after throwing it up to serve as a guide forthe wire.

From the above it will be seen that the wheel can be very quicklyengaged with the wire, as there is a comparatively large space IOObetween the divergent ends of the fork-arms. The fork also acts as ashield for preventing the wire from becoming entangled with the harp andwheel. The object in making the holes in the arms with which the bail isconnected at one side of the axial line of the fork is to allow thelatter to be thrown a little forward of the center when elevated by therope. This will prevent the fork from 'being thrown back until the wireis seated in the center thereof.

The device can be readily applied to the trolley now in common use.

Having thus fully described my invention, what I claim is- 1. Thecombination with the harp and trolley-wheel and axle, of the armspivotally connected intermediate their ends to said axle, the iaringfork at the upper ends of said arms, the bail or yoke pivotallyconnected with the lower ends of said arms and the spring-arms securedto the fork and bearing` against said wheel,substautially as described.

2. The combination with the harp and trolley-wheel and axle, of theflaring fork, the downwardly-extending arms secured thereto andjournaled intermediate their ends to said axle, and having holes neartheir lower ends at one side of the axial line-thereof, the bailconnected with said holes and the down` wardly-extending spring-armshaving their upper ends secured to said fork and their lower endsbearing,` against the trolley-wheel, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto afxedmy signature in presence of two witnesses.

JOHN C. KELLOGG.
